Note: this style has some sizes on pre-order! Please note if your selected size is one of them. If your order contains a mix of in-stock and pre-order items, the order will ship when ALL items become available. If you need an in-stock style ASAP, please place a separate order!

One of our most-requested styles: “a cheeky…that isn’t cheeky.” Tall order, right? Ok, well, we delivered! Per the requests we got, it was important we maintained a similar hip coverage to a cheeky cut, but with fuller booty coverage. Our Rockwell Fuller Coverage Classic Bikini Bottom features the fullest possible coverage for a brief-style bottom (without it looking like a boyshort!), while still keeping the side seam height similar to a cheeky. This bathing suit bottom that fits like underwear has the cut of traditional brief-style underwear, which provides a comfortable, more modest amount of coverage than some of our other swim bottoms. And, of course, in addition to this better-than-seamless bikini bottom providing modest coverage, Rockwell also naturally features our inner grip strip (which is on all of our swim that doesn’t dig in!) so you’ll feel secure without tight seams that squeeze.

Want a fuller coverage bikini top to pair Rockwell with? Try the Thames Scoop Neck Bikini Top! Or, are you looking for a style with even more coverage than Rockwell? Opt for our Compo Hipster Bikini Bottom.

📏 fit note: not sure what size you should get? if you are in-between sizes, we recommend sizing down. your best onewith size should dig in a little at first. then, with a stretch (watch THIS video) it should still fit snugly, but look super-smooth...like no-show undies ☺️ if you DON’T need to ‘warm up your onewith’, it’s a red flag 🚩 that means the suit is too big, and when worn in the water, it will stretch out (like any loose swim would.) we don’t want that! so ensure your suit is fitting swimmingly, pun intended. (stretching the swim does not impact the ability to return/exchange. it's built for this!) 🌊

    Love the coverage!

    I never thought I'd find coverage enough, especially one that wouldn't move at all!! I am SO FREAKING HAPPY!!! My butt never looks good in typical bottoms but when I tried these on and seeing how they don't squeeze or pinch, it's not so bad looking anymore 😏😂

    Not perfect but

    Gets the job done. I’m a lean person but I have no muscle. No tightness to my figure. I’m also very busty. 32G/29/38 size 4/6 in most clothing. Tops med. 5’4.5” for reference. Swimsuits never fit my top. Too big around. Too small cups. Bottoms often times cut in on the sides. These bottoms after “warming” them, look much better than most. I’m very comfortable in them. I can also wear them lower or higher on my hips. They cover just enough of my rear that my conservative parents won’t freak out when I wear this on vacation. I do love that I can pair these with just about any swim top and there’s no weird bulges in shorts like tie side bottoms!
